Summarize the weather and ecological conditions associated with each season?
Answer: Seasons have an enormous influence on vegetation and plant growth. Winter typically has cold weather, little daylight, and limited plant growth. In spring, plants sprout, tree leaves unfurl, and flowers blossom. Summer is the warmest time of the year and has the most daylight, so plants grow quickly. In autumn, temperatures drop, and many trees lose their leaves.

Answer:
A. codominance
Explanation:
Codominance is in which at least two characteristics are involved together of a particular feature get expressed into an offspring.
Both the mother and father's type are expressed. The offspring with alleles A and B for blood type has type AB blood. The alleles are codominant -- neither one alone determines the blood type.

Answer:
Looks like a recessive trait, since both halves of the shape needs to be filled to make the trait active.
The pedigree is explained in the image, and the male is represented by the square and the female is represented by the circle. Here is the sex linked recessive pedigree present in the image.
What does the pedigree explain?The pedigree explains the heritable pattern of traits, such as genetic diseases in males and females, as well as the chances of being diseased, such as with sex-linked recessive diseases, where males have a higher chance of being diseased than females. Here the image explains it is a sex-linked recessive disease because most females are carriers, which means they have a single copy of the recessive allele, but when they pass it on to their sons, they get fully diseased as they need a single recessive copy due to the presence of a single X chromosome.
Hence, the male is represented by the square, and the female is represented by the circle, and here is a sex linked recessive pedigree present in the image.

Compare the chromosome number of the parent cell with that of each daughter cell.
Answer:
In mitosis, the daughter cells have the same number of chromosomes as the parent cell, while in meiosis, the daughter cells have half the number of chromosomes as the parent.
Environmental factors typically activate genes in a cell by causing the cell to —.
Answer:
Environmental factors typically activate genes in a cell by causing the cell to transcribe specific DNA segments to mRNA for translation.
Environmental factors typically activate genes in a cell by causing the cell to transcribe specific DNA segments to mRNA for translation. The correct option is D.
What are environmental factors?This interaction is an illustration of how the environment influences how genes are expressed. In certain circumstances, the environment triggers the expression of particular DNA segments, which results in their transcription to mRNA and subsequent utilization as building blocks for proteins.
Other regions of the genome are left silent or are compelled to do so in the meantime. Mutations or straightforward biochemical interactions between the environment and the genome may cause this.
Therefore, the correct option is D. transcribe specific DNA segments to mRNA for translation.

Energy in an ecosystem flows directly from _______. a. producers to tertiary consumers b. producers to secondary consumers c. tertiary consumers to secondary consumers d. secondary consumers to tertiary consumers please select the best answer from the choices provided a b c d
Answer:
A.
Explanation:
Primary producers use energy from the sun to produce their own food in the form of glucose, and then primary producers are eaten by primary consumers who are in turn eaten by secondary consumers, and so on, so that energy flows from one trophic level, or level of the food chain, to the next.
Energy in an ecosystem flows directly from producers to tertiary consumers. So, the correct option is A.
What do you mean by Ecosystem?An Ecosystem may be defined as an area where organisms of different species are present together in a given time and interact with one another in order to survive.
In an ecosystem, producers produce the energy in the presence of sunlight through the process of photosynthesis. And then passes its energy to primary consumers (herbivores), then primary consumer passes their energy to secondary consumers (carnivores), then secondary consumers pass their energy to tertiary consumers. According to Lindeman, only 10% of energy get transferred to each trophic level.
Therefore, Energy in an ecosystem flows directly from producers to tertiary consumers.

Telomere shortening puts a limit on the number of times a cell can divide. Research has shown that telomerase can extend the life span of cultured human cells. How might adding telomerase affect cellular aging?.
Telomerase is an enzyme that longs telomeres, which are fundamental repeats at the ends of chromosomes whose length is associated with cellular aging.
What are telomeres?Telomeres are specific long tandem repeats located at the ends of all chromosomes in the cells.
These repeats (telomeres) are fundamental during cell growth and cellular aging.
It has been shown that telomerase can avoid the shortness of telomeres and thus can be used to slow cellular aging.

Often, ____________ or basidiomycetes are the fungi involved, and they form several layers of hyphae, one of which envelops the photosynthetic ____________ .
Most of the time in lichen, ascomycetes or basidiomycetes form the fungal part with several hyphae layers enveloping the photosynthetic algal part.
LichensLichens are composite organisms. They are formed from a symbiotic relationship between fungi and algae. The fungi provide shelter and some vital minerals for the algae while the algae provide food via photosynthesis.
Oftentimes, the fungi components are usually ascomycetes or basidiomycetes. They form a network of hyphae around the photosynthetic algae as a form of protection.
